I've heard about miracles in Shirdi, but I am doubtful. How did Sai Baba handle people who came with a 'clinical scrutiny' or questioned his abilities?

The story of Boss Dharamsee in Chapter 35 provides a clear example of how Sai Baba addressed skepticism. Dharamsee arrived with a critical mindset, questioning why people came to Shirdi. He was internally troubled when Baba offered him grapes with seeds, which he disliked. He even thought, 'If he is a saint, how does he not know That I do not like these grapes?' In response to this internal doubt, Baba performed a subtle miracle. He commanded Dharamsee to eat the grapes, and upon doing so, Dharamsee discovered they were seedless. This direct experience amazed him, causing his ego and 'clinical scrutiny' to vanish, replaced by love for the saint. This shows that Baba often used personal, transformative experiences to turn a doubter into a devotee.
